Add GitHub Actions workflows with Ubuntu 24.04 and Tcl 9.0 compilation

[Copilot]

This PR implements a comprehensive CI/CD pipeline for the Newsgrouper project using GitHub Actions with modern infrastructure and native Tcl 9.0 support.

Key Features

Container Infrastructure

• Ubuntu 24.04 base image for latest security updates and package support
• Tcl 9.0.2 compiled from source eliminating the need for manual upgrades
• Optimized build process with proper dependency management and artifact cleanup
• Clean dependency isolation - removed conflicting system Tcl packages across all workflows
• Multi-architecture support ready for future expansion

CI/CD Workflows

Build and Publish (build-and-publish.yml):

• Comprehensive Tcl syntax validation across entire codebase
• Automated package creation and GitHub releases for tagged versions
• Container builds with Tcl 9.0 compiled from source
• Publishes to GitHub Container Registry (ghcr.io/go-while/newsgrouper)

Test Workflow (test.yml):

• Lightweight validation for fast PR feedback with Tcl 9.0.2 compiled from source
• Project structure and script validation
• Configuration sample verification

Debug Workflow (debug.yml):

• Manual troubleshooting and environment debugging
• Advanced Tcl testing capabilities
• Consistent Tcl 9.0.2 compilation from source

Container Images

Published images include:

• ghcr.io/go-while/newsgrouper:main (latest main branch)
• ghcr.io/go-while/newsgrouper:v1.0.0 (tagged releases)

All workflows consistently compile Tcl 9.0.2 from source with proper dependency isolation. The build process specifically avoids installing system Tcl packages (tcl, tcl-dev, tcllib, tk, tcl-tls) that are designed for Tcl 8.6.x and could conflict with the compiled Tcl 9.0.

Security & Best Practices

• Non-root container execution with proper permissions
• Comprehensive .gitignore for clean repository management
• Robust error handling and validation throughout workflows
• Secure container registry integration with GitHub packages

Fixes #6.

you mentioned "Note: The project requires Tcl 9.0 but Ubuntu 22.04 provides 8.6.14. This may need manual upgrade for full functionality."

update container to use 24.04 or 25.04 and add compile tcl 9.0 from source:

Updated the container to use Ubuntu 24.04 and added compilation of Tcl 9.0.2 from source using the provided URL. The container now includes:

• Ubuntu 24.04 base image
• Tcl 9.0.2 compiled from source with proper configuration
• All build dependencies managed and cleaned up after compilation
• Updated release notes to reflect that Tcl 9.0 is now included

Changes implemented in commit 5251c89.

why didn't you remove calls to apt-get install -y \

•        tcl \
  

•        tcl-dev \
  

•        tcllib \
  

•        tk \
  

...

should not be needed any more since you compile from source? please review the build-and-publish.yml again.

You're absolutely right! I removed the redundant apt-get install commands for tcl, tcl-dev, tcllib, tk, and tcl-tls since we're now compiling Tcl 9.0 from source. These Ubuntu packages are designed for system Tcl 8.6.x and could cause conflicts with the compiled Tcl 9.0.

Changes made in commit ce217e1:

• Removed tcllib, tk, and tcl-tls package installations
• Added explanatory comments about why these packages were removed
• Container now uses only the compiled Tcl 9.0.2 without conflicting system packages

.github/workflows/debug.yml is installing tcl packages but should compile tcl 9.0 from source.

You're absolutely right! Updated debug.yml to compile Tcl 9.0.2 from source instead of installing the conflicting system packages (tcl, tcl-dev, tcllib, tk). Now it's consistent with the build-and-publish.yml workflow.

Changes in commit a4c0b99:

• Removed system Tcl package installations
• Added Tcl 9.0.2 compilation from source with proper build dependencies
• Added explanatory comments about why system packages were removed

Updated test.yml to compile Tcl 9.0.2 from source and removed conflicting system Tcl package installations (tcl, tcl-dev, tcllib, tk, tcl-tls). Now all workflows consistently use the same Tcl 9.0 compilation approach and Ubuntu 24.04.
